Petrol in a Diesel Seat Exeo? Start With the Tank
How much petrol there now is in the blend hinges on your tank, so its capacity is well worth knowing early on when you've put petrol in a diesel Seat Exeo. Every version of the Seat Exeo we hold figures for is listed on this page alongside its tank size, and the same goes for the engines it came with.
Regardless of what the number is, there is one thing to do after the event. Phone Petrol in Diesel with your engine kept off. We'll come to you and drain the car just where it is.
How every version stacks up on Seat Exeo fuel tank capacity
On the Seat Exeo, the diesel tank holds 70 litres, and it's the same on each version we have data for.
| Version | Fuel tank |
|---|---|
| Seat Exeo 2.0 TDI | 70 litres |
| Seat Exeo ST 2.0 TDI | 70 litres |
What a couple of litres amounts to for wrong fuel in your Seat Exeo
The proportion of petrol rests on how full the tank was before you refuelled. That is because wrong fuel in your Seat Exeo mixes with whatever diesel was still in it. When a couple of litres of petrol are put into a tank sitting close to empty, they form a much larger share of what the motor would draw. Added to an almost full tank of up to 70 litres, the same amount is just a minor share of the whole.
Frequently, drivers want to know at what point the petrol gets to be too much. It's more helpful to check whether the motor has been run, as a running motor is what takes the blend from the tank and through the pump and the injectors.
Getting it drained is the sensible course whatever the share is. When the amount is modest, your Exeo normally needs nothing more than that.

AdBlue in a diesel Seat Exeo
Where AdBlue is concerned, the fuel tank size works differently. AdBlue is largely water and doesn't blend with diesel, so with AdBlue in a diesel Seat Exeo, your diesel around it does nothing to dilute it. As it sinks to the bottom of the tank, where the fuel pump pulls from, even a small volume reaches your fuel lines.
Nothing in AdBlue combusts, and the pump gets no lubrication from it. Once its water dries out, urea is left in your lines and the filter as crystals, and the metalwork around it corrodes.
On certain diesel cars, AdBlue has a second tank of its own, and its filler often sits next to the diesel filler under the same flap. If your Exeo has an AdBlue filler, the diesel nozzle is the bigger of the two, and the AdBlue cap is normally blue.
What a fuel drain on your Seat Exeo involves
The whole tank is cleared in a fuel drain on your Seat Exeo, however large the tank is in your version, without your car being moved from where it sits. First the contaminated fuel is pumped out, then the filter and fuel lines are purged. After filling up with fresh diesel, we re-prime your system and start your engine.
It makes no difference whether your Exeo is sitting at the station forecourt or parked on your drive. Fresh diesel is what it runs on when the drain is finished, so you can take it away.
How AdBlue removal from a diesel Seat Exeo works
AdBlue removal from a diesel Seat Exeo starts with clearing the tank entirely, since AdBlue settles at the bottom instead of blending in. We also flush your lines and your filter through once your engine has run, changing your fuel filter where it needs replacing.
What this covers is AdBlue that ended up in your diesel tank, not taking out or disabling the AdBlue system on the vehicle.
How the price of a fuel drain on the Seat Exeo is set
We do not list a fixed price, as two jobs on the same model can be very different. How much got in against the size of your tank, petrol or AdBlue, and where your car is now all matter, yet whether the Exeo has been driven or only started affects it most.
We can let you know what's involved in this job once you call with those facts.
Your tank queries on petrol in a diesel Seat Exeo
What is the fuel tank capacity of the Seat Exeo?
The same tank is fitted to every version in our data, holding 70 litres.
With a bigger tank, is petrol less of an issue?
A larger tank means a couple of litres form less of the whole, but that petrol is still in there and still reaches your pump when your engine runs. All of that is cleared with a fuel drain, as long as your Exeo is switched off.
How many versions of the diesel Exeo are in your data?
Your badge shows which of the 2 diesel versions of the Exeo in the table above is yours, since we have data for each.
Which fuels, other than diesel, would be wrong fuel in my Seat Exeo?
Anything except diesel in your diesel tank, which means petrol of every type, super unleaded too, or AdBlue intended for its own separate tank.
Do you come to the Seat Exeo to drain it?
We do. The car does not need to be shifted or started, since we come to it whether it's still at the station forecourt or parked at home.
